A 13-month-old girl was found unattended Wednesday morning in an Occupy D.C. tent, U.S. Park Police said, and one man has been arrested on charges related to cruelty to children.

Sgt. David Schlosser said authorities were called around 10 a.m., when several people who are also living in the encampment “heard the kid crying.”

“The fact of the matter is, it was in the mid-40s and it was raining and she was in the tent alone,” Sgt. Schlosser said. “She was in a onesie sitting on some blankets.”

A man returned to the tent during the investigation and admitted the child was his, Sgt. Schlosser said. The man was arrested on charges of attempted cruelty to children in the second degree. Police have not identified the man.

The McPherson Square camp is home to roughly 100 people who have set up tents and other temporary shelters in an ongoing protest against corporate and government greed.

The residents have recently come under fire from city officials for unsanitary living conditions and an increase in the park’s rat population and by federal officials for trampling new grass that was part of a $400,000 park overhaul.
